If you do not like unity, you can just use ubuntu-gnome like me. IMHO, Unity is horrible, but you have the choice to not use it. There is no need to complain.
Criticism does not equal complain. If I find something horrible I'll say so - that's feedback. By your way of thinking, since I don't have to use brainfuck (an intentionally horrible language) I should not mention that it is horrible. You just don't make sense other than patting youself on the back for being 'positive' downvoting the grumpy ones while letting bad ideas forward.
